So you're 30 with no dating experience? Tell me about the real deal. Are you honest, hard working, compassionate? What have you achieved in your 30's? What makes you different from other 30 year olds? I think guys will be wanting to know about those answers than how much of a dating experience you've. It's not like you run a marriage bureau.
I don't know what an old maid is and I don't know what about your personal life would cause guys to not want to date you. If you decide to start dating you may find a guy you like that becomes your buy friend though!
